The second surface comprises a transparent material covering the second surface and the housing includes two or more microphone ports disposed along a parting line between the first surface and the second surface exterior to the transparent material. The housing further includes two or more microphones coupled with the two or more microphone ports. A microphone signal processing system may be utilize to increase directional sensitivity of the two more microphones toward an audio source. An angle detector to detect an angle of the may be utilized to accommodate the directional sensitivity provided by the microphone signal processing system.

BACKGROUND

In modern notebook and Ultrabook™ designs, microphone selection,placement and system design should optimize the user experience forspeech recognition and audio/video conferencing. Typical system designsincluded a plastic or metal bezel surrounding the front glass or clearplastic of the display which allowed the microphone ports to be realizedas simple openings or holes in the bezel that could be fabricated aspart of the injection mold or metal fabrication process.

More recent designs, however, forgo the utilization of the bezel suchthat the front glass or surface covers the entire front display surface,also known as the B surface of a clamshell design. In order to providemicrophone ports, holes could be drilled into the front glass or clearplastic where the original holes in the bezel were located for themicrophone ports, but such drilling involves additional manufacturingsteps for making the front glass or clear plastic and may result inmanufacturing fallout of the front glass or clear plastic and/or of anyincluded touch screen components, resulting in increased productioncosts.

Furthermore, the spacing of microphone port 126from microphone port 128 by distance, d, may be accommodated in terms ofthe wavelengths of the sound being processed at a particular frequencyor frequency bin of frequencies being processed such that differentamounts of delay may be applied for different frequencies or frequencybands. Likewise, microphone input beam steering system may receive asecond microphone signal 514 as y₁(t) which is delayed in time via asecond delay unit 516 to provide a second delayed microphone signalw₁(t). The two delayed microphone signals are combined via summer 518 toresult in a beam steered microphone signal z(t). By selecting an amountof delay provided by first delay unit 512 and/or second delay unit 516,microphone input beam steering system 500 may provide directionalsensitivity of the input audio signal so that the sensitivity to thedirection of the source of the audio may be increased, maximized, ornearly maximized.
